In 2011, Pucci orchestrated a hit-and-run accident to frame Jotaro Kujo's estranged daughter, Jolyne Cujoh. She was sentenced to 15 years at Green Dolphin Street Prison. This was a calculated trap to lure Jotaro out of hiding.
When Jotaro arrived to break Jolyne out, Pucci ambushed them using his Stand, Whitesnake.
Whitesnake possessed the ability to extract a person's spirit and memories in the form of physical, readable compact discs.
Pucci successfully stole both Jotaro's Memory Disc (containing the instructions for "Heaven") and his Stand Disc (Star Platinum), leaving Jotaro in a fatal, comatose state.
